provides a pair of supporting guides on.

the :trent and rear faces of the axle and continues supporting the guides in the saine plane above the axle, where the guides are on opposite sides of the intermediate portion 2Q which has the same width as the axle. T he wedge is provided with a groove 29 on its under side, which is designed to straddle the intermediate portion 22 o' the strap or to straddle the axle according to the position of the wedge. When the wedge is moved toward the swivel of the axle it. slides downwardly on the guides of the seat into idle position, the Wedge strad-` dling the axle. When it is desired to block the superstructure, the wedge is forced out` wardly, riding up on the inclined guides and coming into a position where a portion or all of the wedge straddles the internie` diate parl: 22 of the strap.

To conveniently edect the movement of the wedge and hold it in desired position, l pivot to the side of the wedge a link 30. The pivoting is shown as effected by a suitable cap screw 3l. The link extends inwardly between the face of the upper portion Q5 of the seat and a stirrup 35, which is secured to the side ol the seat by screws 36. The link is provided with a handle 37; on its under face it has a ratchet rack 38 which cooperates with an inclined abutment 89 'formed on the inner face of the stirrup. By' taking hold of the'handle 37 the operator may pull the link and wedge outwardly, the wedge sliding upwardly on the seat until it abuts the under face of the Ibeam ll. T he ratchet rack and the abutment 39 hold the wedge in this position, the link resting by gravity in engagement with the stationar)r tooth. Villen desired to release the wedge, it is only necessary to knock the handle 3T upwardly, releasing the link and allowing the wedgelto slide or be pushed downwardly.

lt `will be seen that there is a considerable range ot'position for the wedge with -it still beneath the -beam ll. This enables the wedge on one side to stand higher than that on the other in case it is desired to block the ysulla-structure when the axle is not truly horizontal. Furthermore, this range ol po- 'silion enablesl the blocking to be etl'erlive i'lf [be axle is turned at somewhat oll an angle lo the normal transverse position.

Xlr blocking device is easilyv attached to existing machines; it is cheap and simple, and there is nothing about it to get out of order,

llaving thus described myinvcntion, what l rlaini is: l A

l. ltr a truck, thev combination, with a siiperetrnf'ture. of an axle connected therewith. a seat mounted on axle and providing inclined guieleways on the front and" rear fares of the axle, and a wedge slidable meneer on said'guideways and adapted to coact with the under side of the superstructure, sa1d wedge being recessed on its'under side to straddle the axle'.

2.-.The combination, with an axle and a Superstructure, ot' a seat secured to the axle and having a pair of inclined guideways lying on opposite sides of the axle and extending above it and having a connectingl portion resting on the upper face of the axle, and a wedge resting on the guideways and' adapted to engage the superstructure.

3. In a truck, the combination, with the superstructure and axle, of meansI including a wedge designed to form a distance piece between the superstructin'e and axle, a bar for moving the wedge and provided with a ratchet rack on its lower edge, a handle projecting from its side, and a stationary tooth adapted to engage such rack and hold the wedge in adjusted position.

fl. rlhe combination, with the axle and superstructure, of a seat straddling the axle and providing inclined guidewa-ys on it; front and rear sides, a wedge slidably mounted on such guideways, a link connected with the wedge provided with a handle and with a rack, a guide for the link, and a tooth designed to cooperate with the rack sin various positions on the wedge.

In a truck, thecombination of an axle, a superstructure swiveled thereon, a seat in the forni of a U-shaped strap extending onto the front and rear sides of the axle, a wedge slnlablv mounted on such seat, a link connected'with the wedge and provided with a handle, and a stirrup on the side of the strap forming a guide for the link.

il. ln a truck, the combination, with a superstructure having a pair of parallel I- beams, a transvel steering axle intermedi- 'ateliP swiveled to the superstructure, a pair otseals secured to the axle on opposite sides oi itsI center, each seat providing inclined guideways extending outwardly and upwardly beneath the I-bzams, wedges riding on such guideways and adapted to engage the under tace of the. I-beams, links secured to the 4said wedges and extending inwardly, and means adapted lo engage the links to lock the wedges in adjusted position.

7. ln a truck, the combiuatiom'with the superstructure having a pair of parallel I- heanis, a transverse. steering axle intermedialelv swiveled lo the superstructure, a pair o'f seats secured to the axle on opposite sides ot' its center, each seat providing inclined guideways extending outwardly and upwardbr beneath the I-beaxns, wedges riding on .such guidewavs and adapted to engage lhe under tare of the I-beains, said wedges being recessed on their under faces to enable .lhein lo straddle the axle, links pivoted to lbe wedges and extending inwardly and having ratchet teeth on their lower edges,

for the links, and e stationary tooth :linieeeh linlr designed lo eolici: with the link lan liold ille wedge in adjusted position.

lin e, trnelrE lne combination, with a sui rlgruelure :ind laxle, of inclined seats curried by llie axle and ineliningg,r downwardly mid inwardly, wedges riding on said seats, im nivomlly connected lo the Wedges and zending inwardly alongside of the axle opwelling *elle wedges, 'and'mea'ns for "ng lzlie bers lo hold them in locked il l, llie combination, with n. superstructure steering erde connected thereto, of lin seal' mounted on the steering axle, lieving an inclined under fece rest .lie sedi', sind adapted no abut en under ffice of the superstructure, said wedge being recessed on its under side izo straddle the axle, and means for holding the Wedge in desired posilion.

10. The combination, with en axle and snperstrueture, of n pair of inclined guideways secured to lie opposite sides of the eide, a wedge recessed on its under side Lo stmddle the axle :ind resting on said guilleways, and ineens for lockinu the wedge in various positions on Llle gui( ewzlys.
